It's not just 'the young' any more is it? As you say there are people in 40's who can't get on the housing ladder. I'm one of them. That isn't 'the young' that's half the population!
How to help half the population?
Immediately wealth redistribution, with a view to wealth reconfiguration, so that wealth is never spread so unequally again.
That's a little vague, so... what I'd like to see is an immediate ban on buy to lets, tax what's there out of existence. We do need more houses built: or rather more dwellings. Obviously none of us want to see cities the size of Derby being built every year, apart from the visuals it cuts into our food production capability, so that also means we're going to have to look at numbers (and I don't mean blame te immigrants). Difficult but no one said this would be easy.
More jobs in the public sector. Schools are an obvious target. We haven't got enough school places and we need more jobs, so more schools. That was easy.
More jobs in the private sector. Here it gets more difficult again. My feeling is our economic model with it's emphasis on efficiencies of scale does local people much good. We don't want one multinational efficiently producing one good and employing 10000 people (plucking figures out of thin air here): we want 10 local, regional or national companies producing that good and employing 100 000 people. My feeling is that the private company is A. Bad. Thing. and we would all be much better off with only co-operative companies. There must be a balance somewhere: right now we're at the wrong end of one scale.
Food production similarly, there are far too few people involved in food production and far too many heavy machines damaging the soils.
A living wage for all jobs, so that you can do an honest day's work for an honest day's pay and get an honest day's living out of it, with no need for state handouts to go right back into private shareholder hands.
It is a mantra of our times that the state doesn't owe you a living. I begin to think that it does, or rather it owes you the opportunity to make a living. Those opportunities seem to be thin on the ground and reducing fast, or has no one else seen the increase in computers over people in supermarkets and banks. We need as a society to have a damned good think about our relationship with technology, or what on earth people are going to do to survive when technology takes all the jobs.
Well that should give some fuel for the flames!
